Question

public static String calculateRFC2104HMAC(String data, String key)
throws java.security.SignatureException, java.security.NoSuchAlgorithmException,
java.security.InvalidKeyException {
String result;
// get an hmac_sha1 key from the raw key bytes javax.crypto.spec.SecretKeySpec

signingKey = new javax.crypto.spec.SecretKeySpec(key.getBytes(), \"HmacSHA256\");

// get an hmac_sha1 Mac instance and initialize with the signing key javax.crypto.Mac

mac = javax.crypto.Mac.getInstance(\"HmacSHA256\"); mac .init(signingKey);

// compute the hmac on input data bytes

byte[] rawHmac = mac .doFinal(data.getBytes());
// base64-encode the hmac

result = org.apache.commons.codec.binary.Base64.encodeBase64String(rawHmac);

result = java.net.URLEncoder.encode(result.trim(),\"UTF-8\");

return result;
}

我很难将此算法应用到Javascript中。我有一个例子可以使用，但我一路上做错了，它永远不会输出正确的hash_code。

这是我必须使用的示例测试用例。

数据： V2 /资产ipGLN = 1234＆安培; senderGLN = 1234＆安培; APP_ID = 3cea2db2＆安培; TIMESTAMP = 2012-12- 06T13：08：02Z

键：6b904a0c5ceefa991b2ebc9cfec202b6

生成的哈希码，即结果：4F7rjpsRpR0IEy12EfAFShjS9VOxpisVgb8ywavqRrI％3D

因此，使用hash_code参数的请求URL将为：

https://digasset.preprod.1worldsync.com/V2/assets?ipGLN=1234&senderGLN=1234&app_id=3cea2db2&TIMESTAMP=2012-12-06T13:08:02Z&hash_code=4F7rjpsRpR0IEy12EfAFShjS9VOxpisVgb8ywavqRrI%3D

如果有人对正确实施上述内容有任何见解，我将不胜感激。

到目前为止，这是我的实施。

var temp_test_key = "";
var test_key_bytes = encodeTextToUtf8(test_key);
for(var i = 0;i<test_key_bytes.length;i++)
{
    temp_test_key+= test_key_bytes[i];
}  
var hmac = CryptoJS.algo.HMAC.create(CryptoJS.algo.SHA256,temp_test_key);
hmac.update(test_string);
var hash = hmac.finalize();
var hashInBase64 = CryptoJS.enc.Base64.stringify(hash);
document.write(hashInBase64);

谢谢。

我甚至试图将其重做为vb.net ..但它仍然不是同样的结果..

Function SignMessage(key As String, message As String) As Byte()
    Dim encText As New System.Text.UTF8Encoding
    Dim btKey() As Byte, btMessage() As Byte
    btKey = encText.GetBytes(key)
    Dim myhmac As New HMACSHA256(btKey)
    btMessage = encText.GetBytes(message)
    Return myhmac.ComputeHash(btMessage)
End Function


Sub Main()
    Dim testString As String = "V2/assets?ipGLN=1234&senderGLN=1234&app_id=3cea2db2&TIMESTAMP=2012-12-06T13:08:02Z"
    Dim Hash() As Byte = SignMessage("6b904a0c5ceefa991b2ebc9cfec202b", testString)
    MsgBox(System.Convert.ToBase64String(Hash, 0, Hash.Length))

End Sub

我需要帮助为1worldsync DAM API实现此算法
